“…They are generally slower acting than other chemicals, but may last longer. These practices might not only reduce FW, but also improve the control of other pest and diseases and enhance productivity (Pattison et al, 2014 ; Haddad et al, 2018 ). However it is important to keep in mind that the success of these practices appears to be genotype-dependent and linked to the resistance level to FW.…”

“…However, quantitative resistance linked to cultural and biological practices have been effective in different scenarios allowing farmers to grow susceptible varieties. In Brazil, for instance, Prata-type cultivars have high market value and are susceptible to FW, but combining resistance with cultural practices growers can cope with the disease and make the banana crop profitable (Haddad et al, 2018 ). Growers in Colombia have also adopted a two-cycle strategy to produce Gros Michel, rotating production before pathogen inoculum builds up in the soil.…”

Fusarium Wilt of Banana: Current Knowledge on Epidemiology and Research Needs Toward Sustainable Disease Management

Banana production is seriously threatened by Fusarium wilt (FW), a disease caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc). In the mid-twentieth century FW, also known as “Panama disease”, wiped out the Gros Michel banana industry in Central America. The devastation caused by Foc race 1 was mitigated by a shift to resistant Cavendish cultivars, which are currently the source of 99% of banana exports. However, a new strain of Foc, the tropical race 4 (TR4), attacks Cavendish clones and a diverse range of other banana varieties. Foc TR4 has been restricted to East and parts of Southeast Asia for more than 20 years, but since 2010 the disease has spread westward into five additional countries in Southeast and South Asia (Vietnam, Laos, Myanmar, India, and Pakistan) and at the transcontinental level into the Middle East (Oman, Jordan, Lebanon, and Israel) and Africa (Mozambique). The spread of Foc TR4 is of great concern due to the limited knowledge about key aspects of disease epidemiology and the lack of effective management models, including resistant varieties and soil management approaches. In this review we summarize the current knowledge on the epidemiology of FW of banana, highlighting knowledge gaps in pathogen survival and dispersal, factors driving disease intensity, soil and plant microbiome and the dynamics of the disease. Comparisons with FW in other crops were also made to indicate possible differences and commonalities. Our current understanding of the role of main biotic and abiotic factors on disease intensity is reviewed, highlighting research needs and futures directions. Finally, a set of practices and their impact on disease intensity are discussed and proposed as an integrative management approach that could eventually be used by a range of users, including plant protection organizations, researchers, extension workers and growers.

“…This fungus produces chlamydospores, resistant structures that can survive long periods in the soil (PLOETZ, 2015;PEGG et al, 2019). Cultural, chemical, and biological control methods have not been effective in controlling the disease (TUSHE-MEREIRWE et al, 2000;KARANGWA et al, 2016), consequently, identification of a 'Prata-Anã' somaclone resistant to Fusarium wilt race 1 that maintains other agronomic and sensory characteristics of the original cultivar is essential to protect the cultivar and ensure that it continues to be a source of income for farmers, especially given its preference by Brazilian consumers (IBGE, 2016;MOSTERT et al, 2017;HADDAD et al, 2018).…”

“…In addition, the pathogen produces resistant structures called chlamydospores which enable it to survive in the soil for many years (PLOETZ, 2015). Cultural and biological disease control practices are not efficient for controlling Foc, especially with high inoculum pressure in very susceptible cultivars, but have shown promising results when associated with less susceptible cultivars with quantitative resistance (HADDAD et al, 2018). So far, the results clearly indicate that the most viable disease management strategy is the development of resistant cultivars (REBOUÇAS et al, 2018;ARINAITWE et al, 2019;GONÇALVEZ et al, 2019).…”

Selection of somaclonal variants of the cultivar ‘Prata-Anã’ for resistance to Fusarium oxysporum f. sp. cubense race 1

The banana tree is one of the most cultivated fruit globally; however, some diseases significantly affect its production, such as Fusarium wilt. The most appropriate measure for controlling this disease in areas with inoculum pressure is the use of resistant cultivars. Therefore, this study aimed to generate banana somaclones of the cultivar ‘Prata-Anã’ resistant to Fusarium wilt by inducing somaclonal variation. ‘Prata-Anã’ stem apexes were established in vitro in MS culture medium and, on a monthly basis, subcultivated in AIA and adenine sulfate supplemented MS medium with added plant regulators: 6-benzylaminopurine (BAP, 4 ml L-1), Thidiazuron (TDZ, 1 ml L-1), and Paclobutrazol (PBZ, 10 ml L-1). The treatments were: T0: no regulator, T1: BAP, T2: TDZ, T3: PBZ, T4: BAP + TDZ, T5: BAP + PBZ, T6: TDZ + PBZ, and T7: BAP + TDZ + PBZ. After the twelfth subculture, the regenerated plants were planted in boxes containing sterile soil infected with Fusarium oxysporum f. sp. cubense, and evaluated after 90 days for resistance to the pathogen. Somaclonal variants T2-1 and T2-2, generated in Treatment 2, with TDZ, were selected as resistant. This result is promising for the launch of a new Fusarium race 1-resistant banana variety.

“…Mixed plantings in smallscale or subsistence agriculture, in which diverse banana cultivars are planted with different crops, often develop more moderate losses than if they had been planted in monocultures [10]. Planting of Foc-tolerant or Foc-resistant cultivars accompanied by cultural practices help to improve the disease incidence and increase the crop yield [82]. Mixed culture system involving legumes, cereals, and multipurpose trees in the banana plantation can also improve the production yield of banana and develop improved tolerance against the disease [83].…”

Fusarium wilt, caused by Fusarium oxysporum f. sp. cubense (Foc), is one of the most threatening fungal diseases affecting banana plantations across the globe. It was first discovered in Australia in 1874 and has now spread to numerous different regions in the world hinting at the persistency of the pathogen. Various management strategies have been devised aiming mainly on improving the plant's tolerance or suppressing the infection. Fungicide is commonly used to control the disease spread, but it does not provide total protection to the plants besides displaying selective effectiveness on certain Foc strains. Alternatively, farmers apply crop rotation, rice hull burning, biological soil disinfestation, and compound-supplemented soil in their banana plantations. Studies have also shown that certain biocontrol agents manage to curb the disease threat. Selection of somaclonal variants and genetic manipulation via induced mutagenesis and transformation are also among the alternatives that have been implemented in producing Fusarium-tolerant and Fusariumresistant banana plants. This chapter will describe Fusarium epidemics in banana, the effectiveness and challenges of different management approaches, as well as the future alternatives that can be adopted by taking advantages of the latest advances in omics technologies.
